Yes I’m familiar with Siegfried and the rest of them and am myself using a ton of alternative cancer therapies. I have lung cancer, caught early, no mets. Had radiation to shrink it and am currently on a checkpoint inhibitor. I too decided to hold off on the chemo, at least for now. Over 95% of my tumor expresses the PDL-1 mutation so chances are the checkpoint inhibitor I take will work extremely well on that or so I hope.
Very best to you. I pray you will beat this.
